如何在Android中获取多行TextView的最大宽度？

Question

I am new in android and facing the problem to get the maximum width of the multiline TextView.

I used textview.getWidth() and textview.getMeasuredWidth() but both gives garbage value.

I used also textview.length() , but retuns zero.

Please note that i have not set the maximum width of the TextView.I want to get it runtime.

Answer 1

TextView_name.setLayoutParams(new LayoutParams(250,LayoutParams.WRAP_CONTENT));

通过使用上面的代码，我们可以动态设置textview的宽度

Answer 2

I would try to use getWidth() . If you want to do that though, you have to be careful when you call it. It only makes sense after the view hierarchy is laid out. That means that trying to check onCreate , onStart or even onResume will probably not get the results that you want. As an experiment, you can call it in a click handler of a button and you should see the expected value correctly being returned. I can't really say any more about where you should get it without knowing what you want to use it for.
